Question

我正在使用resilience4j断路器，并且无法使用Prometheus Servlet客户端导出度量标准。我正在部署到jbossas7服务器，但是/ metrics端点未显示任何内容。有任何想法吗？我正在将断路器注入一个Bean中，该bean与下面的断路器初始化代码（位于工厂中）一起正常工作。

调试代码时，我看到断路器已制成并已在collectorRegistry中注册。但是，当将其写入simpleclient servlet的servlet中时，不会将任何内容写入输出。它只是跳到客户端库代码中的finally块

断路器启动

public CircuitBreaker getInjectedCircuitbreaker(InjectionPoint injectionPoint) {
    Circuitbreaker breaker = injectionPoint.getAnnotated().getAnnotation(Circuitbreaker.class);
    CircuitBreaker circuitBreaker = circuitBreakerRegistry.circuitBreaker(breaker.breakerName());
    collectorRegistry.register(CircuitBreakerExports.ofCircuitBreakerRegistry(circuitBreakerRegistry));
    return circuitBreaker;
}

Prometheus指标servlet不显示任何指标
